IPA [w̃]
AS [ũ̯]
positional variant (does not occur in isolation)
Based on Maciołek & Tambor (2012)
Voiced: the vocal folds are in contact, the air coming from the lungs causes them to vibrate.
Non-palatalized: the middle of the tongue is in a neutral position, it does not take part in the articulation.
Labio-velar: the lips move forward and are rounded, at the same time, the back of the tongue gets close to the soft palate.
Nasal approximant: the articulators get closer than with vowels but less than with fricatives. The soft palate moves away from the back of the pharyngeal cavity and enables the free flow of air through the nasal cavity and out.
